2.) Definition of direction of rotation
After the end of the measurement, it must be verified, by means of a test travel operation, if the
internal direction of rotation of the electric field and the direction assignment in the lift correspond to
one another. Provided that the drive has been in operation before (e.g. replacement of encoder), no
special requirements must be considered in this regard.
Internal electric field
The motor phase sequence must be adjusted to the direction of rotation of the rotary encoder.
To do this, proceed as follows:
•
Perform static calibration
•
Check if travel operation is possible. If the direction is correct, the drive will turn (with torque),
although the direction assignment to the lift might not yet be correct. If not, the drive will get
stuck electrically at some position and stop at high current without torque. An error "
No
startup
" or "
Wrong tacho polarity
" will be displayed. In menu <
Inputs/outputs
> <
Encoder
input
>, the encoder direction must be changed and the measurement must be restarted.
After this measurement, the internal direction assignment will be correct and the drive will
turn with torque.
Direction assignment of lift
To invert it, 2 motor phases and the direction of rotation of the encoder must be changed in menu
